clk: qcom: apss-ipq-pll: Fix 'l' value for ipq5332_pll_config
[ Upstream commit 5b7a4d3d2b33398330aef69e0ff5656273483587 ]
The earlier 'l' value of 0x3e is for 1.5GHz. Not all SKUs support
this frequency. Hence set it to 0x2d to get 1.1GHz which is
supported in all SKUs.
The frequency can still increase above this initial configuration
made here when the cpufreq driver picks a different OPP.
